20% Tax Credit Basics

This information pertains to the 20% federal tax credit for the rehabilitation of historic properties.

  • The amount of credit available under this program equals 20% of the qualified expenses of your rehabilitation.
  • The tax credit is only available to properties that will be used for a business or other income–producing purpose, and a "substantial" amount must be spent rehabilitating the historic building.
  • Your building needs to be certified as a historic structure by the National Park Service.
  • Rehabilitation work has to meet the Secretary of the Interior’s Standards for Rehabilitation, as determined by the National Park Service.

Before applying, consult your accountant or tax advisor to make sure that this federal tax credit is beneficial to you. Certain income and other restrictions may have a bearing on whether an owner is able to use the credit. IRS administers the Department of the Treasury’s involvement with the Federal Historic Preservation Tax Incentives Program. The IRS has provided written guidance on these complex federal regulations which is available as easy-to-understand guidance in IRS Information.

PLEASE NOTE that Public Law No: 115-97 (December 22, 2017) amended the Internal Revenue Code to reduce tax rates and modify policies, credits, and deductions for individuals and businesses. Section 13402 modified the 20% Historic Rehabilitation Tax Credit, repealed the 10% tax credit for the rehabilitation of non-historic buildings, and provided transition rules for both credits. These and other changes to the Internal Revenue Code may affect a taxpayer's ability to use the 20% tax credit. Applicants requesting historic preservation certifications by the National Park Service and those interested in the use of the credits are strongly advised to consult an accountant, tax attorney, legal counsel, or the Internal Revenue Service regarding the changes to the Internal Revenue Code related to Public Law No: 115-97.

Read the annual reports on nationwide use of the historic preservation tax credit.
